Former Detroit Mayor Kwame Kilpatrick was convicted Monday of corruption charges, ensuring a return to prison for a man once among the nation’s youngest big-city leaders.

Jurors convicted Kilpatrick of a raft of crimes, including racketeering conspiracy, which carries a maximum punishment of 20 years behind bars. He was portrayed during a five-month trial as an unscrupulous politician who took bribes, rigged contracts and lived far beyond his means while in office until fall 2008.

Kilpatrick wore a surprised, puzzled look at times as U.S. District Judge Nancy Edmunds read the jury’s verdict: guilty of 24 charges, not guilty on three and no consensus on three more. Kilpatrick declined to speak to reporters as he left the courthouse.

Prosecutors said Kilpatrick ran a “private profit machine” out of Detroit’s City Hall.

The list of corrupt Detroit area politicians is lengthy. The most recent include:

Monica Conyers: Former Detroit City Council member pleaded guilty in 2009 to federal bribery charges. She served 27 months in a federal prison and then several weeks in a halfway house before her release in January. She’s now on home confinement until May.

Alonzo Bates: Former Detroit City Council member convicted in 2006 of federal charges that he put relatives on the city payroll. Bates began his 33-month sentence in 2009.
